Principle：
VDD is to be added in the voltage treated on programming chip in Fig. 2, is defined as electric terminal voltage in the present invention, VddCtrl,
PDA is the I/O port of control element.VddCtrl is the open and close for controlling vdd voltage, is defined as in the present invention automatically controlled
Terminal voltage processed.PDA pins are whether control VDD is connected with GND.Before treating that programming chip starts programming, programming chip is treated
It is not added with power supply, that is to say, that vdd voltage 0.
When programming flow starts, PDA is low level, and it is high level that VddCtrl, which is opened, and due to R55 presence, VDD can not
The magnitude of voltage at VDD_I points in Fig. 2 is directly reached, only reaches certain voltage value, when triode Q12 is turned on, VDD can just reach
The process of one fast powering-up, the flow are to prevent when VDD and the GND short circuit of programming chip, to fever writes hardware strap
To damage.So the protection circuit in dotted line frame is particularly significant.
In software, after it be high level to set pin VddCtrl, delay certain time interval T 1, i.e., when current default electric
Between, then start to squeeze into the burning sequential for treating programming chip.Now, there is electric capacity if treating the power end of programming chip, i.e. vdd terminal has

One of the method for the power-on time Self Adaptive Control in the present invention is further illustrated with the flow in Fig. 3 below
Embodiment：
During using fever writes programming chip, programming operation can be carried out by button.Herein, long-button function is changed,
, can be with entry time automatic adjusument pattern after long keying 3 seconds, this 3 seconds are the default regulation opening time recited above, should
Time value can be modified and set, and " Time Testing ... ", regulation are completed for display on the LCD display of fever writes
Afterwards, display " TimeTest OK ", can not such as be adjusted, for example non-correct placement chip situation, LCD display show on LCD display
Show " TimeTest Err ".Default power-on time T2 after being adjusted.
Herein, so that the control flow in the electrifying control circuit and Fig. 3 in using Fig. 2 is come programming MCU chip as an example, write from memory
In the case of recognizing, on VDD after electricity, time delay 200us, you can normal programming.If necessary in the case where there is external capacitor
Programming is carried out, it is necessary to increase time delay, the time is relevant with external capacitive size.Now in the case of default time 200us,
Normal programming can not be carried out, if now needing the programming chip, in the case where program can not be changed, external capacitive can only be torn open
Or modification fever writes hardware.Now push button 3 seconds, fever writes, which enter, automatically adjusts time state, internal after adjusting successfully
Default power-on time T2 after being adjusted, subsequently again programming when, the upper electric extension time increases to T2, during programming
The power-off delay time also increases to 3 × T2 so that during vdd voltage can rise to VDD_I, and earth terminal and drop to 0, i.e.,
Level it is identical.The current default power-on time of the T1 as present invention in Fig. 3, T2=T1+2ms；T2 is the present invention's
Default power-on time after adjustment, then the default power-on time value after adjustment is carried out more to current default power-on time
Newly.
In addition, the technical scheme described in the present embodiment is before programming chip, by way of long keying, automatic
To the upper electricity required for the programming batch chip and power-off delay time, the power on delay time is current default upper electricity herein
Time, power-off delay time are discharge time mentioned above, to meet the normal programming of the batch chip.It is same from now on
During the normal programming of batch chip, it is only necessary to short-press button, open normal programming flow.
In consideration of it, upper computer software can be utilized, allow and be manually entered time parameter values, to obtain the upper electricity of relatively good one
And power-off delay, for ensureing the normal programming of a batch chip.But the program is disadvantageous in that, it is necessary to first connect
Computer, and need to continuously attempt to be manually entered time value, can just get one can be with the parameter value of programming chip.Cause
This, is a kind of preferred embodiment by the way of by key control, but the present invention is not limited only to such a regulative mode.
The system and method for realizing fever writes chips power-on time Self Adaptive Control in the invention is employed, is had such as
Lower beneficial effect：
(1) employing button adaptively sets the scheme of power-on time to realize to the controllable of power-on time, in regulating time
During, the power-on time that can make the normal programming of chip is obtained, the time can meet the burning of the chip of a batch
Write demand, in power process, using discharge circuit, reach the process faster discharged, it is short that the program does not influence fever writes not only
The function of road protection, compared with extending the set time, also substantially reduce the time；
(2) present invention can have various power-on time demands in the case where ensureing to protect fever writes for programming
Chip；
(3) without carrying out the electric capacity on different time modifications, or dismounting PCB to different PCB again；
(4) for batch programming, shortening time that can be relatively good, programming efficiency is ensured.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that it can still make
Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, specification and drawings are considered as illustrative
It is and nonrestrictive.
